Features POWERLINE+ 115C Maximum Case Temperature -40C MinimumTemp. DC/DC-Converter Built-in FCC/EN55022 Class B Filter with 3 year Warranty ICE 2:1 Wide Input Voltage Range 40 Watts Output Power Technology* Ribbed or Baseplate Case Styles Min. Efficiency of 87% 3kVDC Isolation Low Quiescent Current 40 Watt Description 2:1 Single & The RPP40 series 2:1 input range DC/DC converters are ideal for high end industrial applications and COTS Military applications where a very wide operating temperature range of -45C to +120C is required. Although the case size is very compact, the converter contains a built-in filter EN55022 Class B / FCC Level B wit- Dual Output hout the need for any external components. The RPP40 is available in two case styles: the ribbed case and the base- plate case for high vibration, bulkhead-mounting or for passive cooling applications. They are UL-60950-1 certified.
